Abstract

The invention relates to a power head of a drilling rig, which comprises a power machine, a clutch module and a gearbox, wherein a power-machine output shaft is arranged in the power machine, the clutch module comprises a centrifugal clutch, a clutch plate and a key, the gearbox comprises a gearbox shell, as well as an input shaft, a drive shaft, an output shaft and nine gears are arranged in the gearbox shell, the power-machine output shaft is connected with the clutch through the key, the clutch is arranged in the clutch plate, the clutch plate of the clutch module is connected with the upper end of the input shaft of the gearbox, the output shaft of the gearbox extends out of the outside of the gearbox shell from the lower surface of the gearbox shell, a water jacket is fixed on the lower surface of the gearbox shell, the water jacket is sleeved on the output shaft, and a water nozzle is fixed on one side of the water jacket. The power head disclosed by the invention is light in weight, small in volume and high in drive efficiency; the power head has three gears, namely, high, medium and low gears, thereby meeting the needs of different output rotational speeds; the power head is compact in structure, and improves the flexibility and reliability of drilling rigs.

Description

technical field [0001] The invention relates to a power head, in particular to a portable and multifunctional drill power head. Background technique [0002] For a long time, our country has faced great difficulties in prospecting in shallow coverage areas with inconvenient transportation. Due to the existence of the overburden layer, the conventional geochemical detection method loses its due effect. The technical method combining shallow drilling and chemical prospecting has become an effective new method for prospecting in overburden areas. At present, this prospecting method has been generally accepted by the majority of geochemical prospecting workers. [0003] The surface landscape in the shallow coverage area is complex and diverse, including forests, swamps, deserts and Gobi, and the transportation is inconvenient. In order to realize the requirements of fast drilling, sampling and fast transfer, the drilling rig needs to be made light and easy to carry manually. ...
